All now seemed encouraging, and he felt thankful to God that he should soon see his parents and sisters again. But while sailing in the Gulf of Mexico, the vessel was attacked and taken by two Spanish frigates of superior force, and the crew were carried prisoners to Havana, in the Island of Cuba. Here Clark remained a prisoner of war nineteen months. Formerly the Spanish authorities treated their English prisoners with great cruelty, but since the humane regimen of Admiral Rodney and the orders of the King of Spain, already noticed, their treatment was kind and humane. But to be confined in a prison, though provided with wholesome food and other necessaries, was by no means pleasant; and the time wore away slowly.

A cartel being arranged, Clark and other prisoners were liberated and soon on shipboard.[9] With gladsome hearts and active hands, they heard the boatswain sing out, “heave O!” as the anchor was raised and the sails unfurled to the winds of heaven; and soon they were ploughing the rippling waves towards a land of freedom. The wind proved favorable, and in a few days they were at anchor off Charleston, outside the bar. Here the good fortune of Clark was again reversed. The eye of an infinite Providence was fixed on this man; his steps were mysteriously directed in all his wanderings, and it was needful he should pass through other and more severe trials, until as gold well-refined, he should be fitted for the Master’s use. Mr. Clark expected to be landed in a maritime port, and have eight days allowed him to choose a vessel and berth. But an hour had not passed before a recruiting officer and press-gang were on board, and poor Clark and several others were again pressed on board another man-of-war by British authority.

Surely there is no condition of servitude so galling to humanity, and so directly a violation of human rights, and so subversive of rational liberty, as the infamous press-gang in the British navy. We rejoice that the just and humane sentiments of the age, have mitigated, though not entirely removed, this odious form of despotism in the British government. Through the operation of such oppression, Mr. Clark found himself on board the Narcissus, of twenty guns, and most unwillingly held in the service of George III. Read his own remarks on the subject.

“Now, I was more determined than ever to obtain my liberty. The love of liberty is implanted in our very nature, and nothing can supply the lack of it. We fared well on board the Narcissus; we had the best of fresh meat when it could be obtained, besides butter, cheese, plum-pudding, and a pint of Madeira wine for each day, but all that could not supply the lack of rational liberty.

“The people of the slaveholding States ought to consider this well; for the spirit of liberty is like a magazine full of powder. If it takes fire, it will consume all within its reach, and the danger increases daily. Many slaveholders sincerely conclude that if they work their slaves moderately, clothe and feed them well, the slaves ought to be contented, but Scripture, sound philosophy, and experience—yes, my own experience—prove such arguments to be sophistry. For although I fared on board the Narcissus as well as I could reasonably desire, yet I was more discontented than ever. So I found the old saying verified,—”

‘Feed me with ambrosia;
Wash it down with Nectar;
And what will it avail, if liberty be wanting.’

My desires for liberty and peace were so great, that death or liberty was the constant language of my heart.”

About this time the British evacuated Savannah, and the Narcissus was appointed a convoy to the transports that moved the refugees from that city to St. Augustine. After performing this duty, the ship returned and lay off Charleston again. Orders were issued to sail to New York, and the night previous Clark and his mess-mates were employed in making preparations for the voyage.

After being discharged from duty, and while at their mess, John Scott and John Clark were invited to join another mess and take grog. The proposal was then made to Clark and his messmate, to obtain their liberty that night by swimming to James’ Island, it being from one and a-half to two miles distant. The plan was arranged by Clark to strip in the bow of the ship, all but their trowsers, and swim at first straight ahead in a quartering direction, until they could no longer be seen from the ship, and then turn in the course of the island. He was chosen to take the lead, and he dashed ahead in the direction he had chosen. The others made some delay, as Clark was to turn on his back and wait for them. He found, on trial, the salt water so dashed over his face, that he was compelled to swim for his life. His situation became extremely perilous; the rippling waves dashed in his face and he began to despair of life. And now he became alarmed at the prospect of immediate death, and his sins rushed on his conscience to that degree that even in the perilous condition he was, he dared not to pray for deliverance. The prayers of his mother seemed to ring in his ears, and in his disturbed imagination the spray that beat upon his face were her scalding tears. Like flashes of lightning his sins pierced his conscience, and the terrors of the law, like peals of thunder, rolled over his sinking soul. Such were his views of his sin and guilt, while swimming for his life, that he dared not pray, lest his cries to heaven for mercy should provoke the vengeance of an angry God to sink him in the deep. But let him tell his own experience from his journal at this terrible crisis.

“I expected to launch into the presence of a frowning and sin-avenging God, whose tender mercies for many years I had trampled under my ungodly feet;—I had broken many promises of amendment;—a yawning hell seemed moving from beneath, at the ocean’s depth, to meet me on my sinking. Human language cannot express the agitation of my mind, and such was my perturbation for a time, that my strength failed me to such a degree that I could hardly keep myself from sinking. I would willingly have sunk, but the thought of dying without the hope of mercy, was so terrible that I resolved to swim as long as I could keep my head above water, or until deprived of my senses, or till some greedy shark, of which the harbor was never clear, should devour me, and put an end to my struggling.”

The impression of dying under the curse of God’s violated law, thrilled through his nerves like an electric shock, and he felt in an instant increased vigor, and swam with greater ease. He could not see the land, and when despairing of deliverance, he found a ship at anchor about 200 yards from him, and two miles from any other vessel, and hope inspired his heart and nerved his arms to further effort, and he resolved to board the vessel, knowing that some of the sailors would give him clothes and help him to land. But all was still. Both officers and men were on shore, or in the city of Charleston. He found an old, ragged, and greasy shirt, and a small boat moored to the ship, but conscience demurred: “How can you be guilty of such iniquity, of taking other men’s property, when God has wrought such a deliverance?” But reason responded: “It is no more than I would cheerfully allow others to do to me under a change of circumstances.”

He got into the boat with the least noise possible, cast her loose, and sculled toward the land. A light breeze springing up he hoisted his oar for a mast, the old shirt for a sail, shipped the rudder and sailed for James’ Island. After tying the boat so that it might be found by the owners, he crept into a hay-stack and rested till morning. After waking, much refreshed from the fatigue and exposure of the past night, Clark sought a position where, undiscovered, he might watch the movements of the Narcissus. At sunrise her morning gun boomed over the waters, and with joyful emotions he saw the signal hoisted for her departure. The wind was fair, and the dreaded ship was soon under weigh, and was soon out of sight.
